"We have seen reports about the whereabouts of the Nigerian girls who were abducted," Carney told MSNBC. "We cannot confirm any individual report, I can't get into any intelligence we may have."

Carney also defended the administration from criticism it did not declare Boko Haram, the Islamist organization which has claimed responsibility for the kidnappings, as a terror group during the tenure of former Secretary of State Hillary Clinton.

The administration did impose sanctions against some Boko Haram leaders, and the State Department designated the organization a terror group in November 2013.

"The fact is we have been working with the Nigerian government and others in the battle against Boko Haram," Carney said.
